Download manager for Windows

Download faster. Never start over.

FluxDM pulls every file over several connections at once, picks up where it left off, and grabs web videos in one click.

01 — The machine

Behind the flow, a machine.

The same download, seen from inside: the FluxDM window, the file in glass bricks, the server and its connections.

The engine

Every file is split into segments downloaded in parallel over several connections, then resumed at the same byte after a pause or a cut.

The queue and the schedule

Your downloads wait their turn in queues, start at the time you choose and keep to the speed limit you set.

The extension’s video button

On a web page, the extension adds “Download this video”, with a choice of quality, audio only and HLS or DASH streams (not on every site, and never DRM-protected content).

Also: BitTorrent, FTP, SFTP, WebDAV and metalinks · clipboard monitoring, if you turn it on · link patterns for batches · video tools installed in one click from the menu · no ads, no telemetry, no account.

02 — Simulation

Start. Cut. Resume.

Your turn at the controls: pick 1 to 16 connections, cap the speed, cut the network mid-download. Every connection resumes exactly where it stopped, and one that has finished takes over half of the largest segment left.

From a web page:

Ready. Choose the number of connections, then start.

The interactive simulation needs JavaScript. In short: the more connections, the faster the file arrives, and a cut loses nothing.

The simulation follows our benchmark, where the server caps each connection at 2 MB/s. The video button does not work on every site, and DRM-protected content is never downloaded.

05 — FAQ

Frequently asked questions

Something else? Write to us:
contactus@riyatastudio.com

Windows says “Windows protected your PC”. What should I do?

This is the Windows SmartScreen warning for programs that aren’t digitally signed yet, which is currently the case for the FluxDM installer. Click “More info”, then “Run anyway”.

To make sure the file is intact, compare its SHA-256 checksum with the one in the Download section.

Is FluxDM free? Are there ads?

The download is free and needs no account or sign-up. FluxDM shows no ads and sends no telemetry.

What happens to my data?

It stays on your computer: your download list, history, settings and credentials. FluxDM works offline and only goes online for the downloads you start and the optional features you turn on. Remote access is off by default.

What about sites that require a login?

Sign in to the site in your browser: with your consent, the extension passes your session on to FluxDM. You can also let FluxDM read your browser’s cookies; that setting is off by default. DRM-protected content is still refused.

Why isn’t the extension in the extension stores?

It hasn’t been published there yet. In the meantime, it loads in developer mode in Chrome, Edge, Brave, Vivaldi and Opera, and as a temporary add-on in Firefox, which forgets it every time it closes. The steps are in the Installation section.

Has this version been tested on Windows?

The previous versions were installed and used on a Windows PC by their publisher, and that feedback directly shaped this one. Version 1.3.0 also passes an extensive suite of automated tests, run on Linux; it hasn’t yet been tried on a large number of Windows PCs.

If something doesn’t work for you, tell us: contactus@riyatastudio.com.
